Serial No. 753,007, patented on March 22, .-i 1927, No.- 1,621,682, the present invention haveV ing for its object the provision of improved means vfor supporting the'blower spout of a corn-bushing machinel In the annexed drawings: a Figures 1 and 2 are elevations of opposite sides of a corn-bushing machine embodying` the present invention, Fig.l 1 showing the machine arranged for useand Fig. 2 show-` ingit arranged .for transportation or storage; i F ig.V 3 is a plan 'viewwith the parts arranged as in Fig. 2;` x

Fig. 4 is a rear elevation.'v

The machine is mounted for travel upon wheels land 2, a draft lbar 5 being connected with the axleof the frontwheels 1. T he rear axle 9' is an invertedl channel barv and lshaft carries a pulley 42 which isconnected by a belt a3 with a pulleyfjon the blower ,shaft 4 5. f 1

.A blower and blast spout are provided at the rear end of the machine, as'v indicated at 68 and 69, respectively. vThe blower shaft is mounted in suitable bearings upon extension bars 70,.-afnd 71, thebar 71' beingsecuredtovr and "projecting rearwardly from the rear i inclined frame, baie, white therme 7o is disposed laterally beyond the plane of the Y' bar 16 and is connected by al couplingbar 72 l with a brace`73which is secured at its lowerV end upon the rearaxle and extendsupwardly and inwardly therefrom to the bar V16 to which it "is secured. further supported by posts V7&1 secured to and rising' from thev a-Xle andthe rear end of the sidebar 9, and a post 7 5 risesfrom the side support the rear/,end of the bar v71t We thus provide a strong frame support for the blower and its. shaft and also so brace the ing the rigidity of the frame. Theblower spout'or blast pipe comprises a-rigid section The bari 70, is

75' which rises directly from theiblo'werf68 and hasn turntable 76 at its .upper end. This turntable carries the jointed end .por-

tions of the-spout whereby the;spout'is car! rie'd vin a curVilinearmanner, either for-V wardly or laterally or rearwardly, to'"said vided with aband 82k *having va lang'e'. When the machinejis in use, the flanges 79 jointed portions being` connected ywitha rigid pipe section 77 of the Ausual' length and provvided at its end witha collar or band 7 8hav. ing al Vflange79 and equipped with an eye 80.- A; second straightrsection 81 'is likewise prof and83 arejbolted together Vso' as toformla tight joint, withthe sectionslin aliniement'," so that the chaff and other fwastematter may be delivered"at a point distant fromm. the

machine.' The section 81 is provided at `its delivery end witha deflecting hood y84e wherebythe chaff and other Vmaterial flowing vthrough the spout willbe directeddownwardly tov the ground. The spout `fand blower. are,f of course,vr located at one side of4 Vthe.machine, and to prevent. warpingof the machine through the vibration of the parts in'V operation, we provide abrace 85 which secured at one end to the turntable 76 and is shownasseeured at its opposite en d'to'fthe chine as'the 'blower andthe spout,atb'racev of the upper beam of the. mainfratrie;'V

framebar l2. At the same side of the ma- V VTo supportfthe'blast spout over the' maehine, weV provide a propiconsis'ting of a .straight shank 87 which may besecuredto brackets boltedtov the top ofthe mainframe and has lits upper end turned laterally,asv

shown at 88, a stirrup. or rest 89 being' se v cured upon and carried by the reefeDdofthe Vsaid laterally turned portion.v Thisstirrup 89 is adapted'to fitpartly around the section 77 of the spout when the spout is arranged to project vforwardly over .the machine,l as

shownin 'Figs2 and 3, in which case it i. be vnoted that thelsections 'are separatedand bar 9 at the opposite side offthemachineto' are tied side by'side Vwith' a rope 90. will be seenthat in thisdescribed yand illustrated position of thepro`p, fthe lateral'arm 88 prof..

jects rearwardly'over the 1naehine` and the spoutis arranged in disassembled, com` act over a vroad -or maybe transportedg'while eeonemizingfspaee. 1t 'it be desired to move. .Y

the machine over a road without disconnecting the sections of the spout or blast pipe,

the prop 87 is turned so that the arm 88 will project forwardly and the stirrup will then be properly located to engage under the outer section of the pipe and support the same, it being thus seen that by merely re-v versing the position of the prop the point of support may be disposed at either side of the joint flanges 79, 83, and the spout irmly held whether the sections be coupled or uncoupled.l

s Toi support the spout in its working ,positionywe provide ay mast 91 which has its lower end, in the illustrated arrangement,

resting upon a base block 92 secured rigidly upon the rear bar 16, and it is held againstlateral displacement by a staple or ring 93 which' is iXed upon the side of the brace 86. rlhe arrangement shown permits the mast to rotate about its own aXis it necessary. The

mast is provided intermediate its ends with a lateral bend or ott-set portion 94 adapted to litaround the spout when the spoutis projecting. over the machine. At the upper end -of the mast a hook 9-5 is pivotally mounted to carry the pulley block 96 over which the hoisting cable 97 runs, and the base block 92 and the4 ring 93y are so disposed that they upper end of .the mast will be brought int-o the vertical plane ot the turntable 76 and al ined therewith, the hook being thus permitted to turnk with the spout without causingv entanglement of the hoisting cable. The endv of the cable 97 is secured toa windlass or winding shaft 98 mounted upon the mast in the usual manner. V This mast, when the machine is to be transported, is secured j againstfone .of the side bars 9, as shown in Fig. 2, sothat it will be out or the way and yet will not be apt to be lost. `The mast maybe easily mounted, when the machine is to be set up for use, by a single operator, inasmuch as all that needs to be done is to engage the mast upon the base block and lit thevring or other retaining. member 93 in place. The cable 97 carries a block and hook which is then engaged with the eye 8O upon the spout,after which a slight winding of the cable will lift the spout out of the stirrup 89 and permit it to be swung to the operating position. i The bend or offset 9d in the mast permits the blower to be located closer to the central line ot the machine than has been previouslv done without interference between the mast and the blower spout. Bv winding the cable 97, the spout will be Vlit'ted from the support 87 and then may be swung'easily to any desired position, moving through an arc of 325 before striking the mast, and the mast may be moved in or out of position while the spout is resting on the prop 87. By setting the blower in toward` the center of the machine, we not only re'- duce the width of the machine but also avoid interference between the blower andthe rear wheel which may traclrwith thefront wheel.

Upon the blower shaft, we rsecure a spiral feeder 100 which leads into the blower and overcomes the chokingwhich 3would otherwise be caused by the blower shaft extends ing across the path of the outgoing material.

Having thus described the invention, we claim: n

l'. A corn-bushing machine comprising a frame, working elements mounted within the trame, a blower at the rea-r end ott the frame, a blast pipe extending from the blower and adapted to project over the frame, said blast pipe comprising a plurality of sections and means tor securing` the sections together,

and a prop mounted upon the frame'and having a laterally extending upper arm adapted to support the spout, the prop being reversible to support the spout when Vthe sections thereot are disconnected or when the sections are in alinement.' A

2. In a corn-husking machine, the combination of a frame, an extension at the rear end ot said frame disposed laterally beyond the adjacent side thereof, a brace extending from the lower part of said extension upwardly to the trame, a blower mounted upon the said extension, ,a spout leading from the bloweipa mast mounted on the trame Aat the f side of the extension and having a lat-eral bend to accommodate the spout in a position extending` longitudinallyk over the frame, the mast being rotatable about its own axisr and means carried by the Ina-st for supporting Y the spout in operative position.`

3. In a corn-husking machine, the combination of a frame, a blower at the rear end of the frame, a blast pipe leading from the blower and adapted to extend forwardly therefrom over the frame, and a reversible prop on Athe frame near the front thereofA and having a lateral arm to supp-ort the pipe or projecting longitudinally beyond the Sallie.
